Does lefort 1 make gonial angle better

[Deleted member 7126]

Since the maxilla is cut, the jaw will swing further giving you a better gonial angle/ more forward growth???

No retard it's literally to move the lower maxilla forward. Even the BSSO part most likely isn't gonna change the gonial angles.

no

And what if i get my maxilla shortened. Due to gummy smile. That would make the gonial angle better. Cope harder

Lol no, it's got to do with the ramus bone.

You don't, gaycel. Also stop simping for foids who'll never give you the time of day

CCW

The gonial angle is the angle formed by the ramus and mandible. A Lefort I osteotomy advances or rotates the position of the maxilla.

These are completely physiologically distinct locations, so no, a LF 1 will not change gonial angle under any circumstances.

CCW

Yea that would affect forward growth?

The ghost of Lefort 3 blesses us with his presence.

I’m not sure

but CCW is what gives the gonial angle from what I heard

In the case of an anterior impaction LeFort I then mandibular autorotation would occur. although the actual angle will be the same (the angle from the mandibular body and posterior ramus did not move) the perceived angle would probably be different because the mandibular plane is becoming more parallel with the Frankfurt Horizontal plane.

Yea thats whats i meant

No it doesn’t change. Gonial angle is kind of your base for jaw surgery tbh

 

[NarcyChadlite]

PPL are confusing gonial angle for "perceived gonial angle"/side profile mandible angle relative to horizon.

Under NO circumstances will gonial angle change with lefort (even w/ ccw). The side profile mandible angle however will be closer to horizontal (b/c mangible upswang to align w/ surgically upswung maxilla)

Gonial Angle CAN change w/ bimax ONLY if mandible is reattached with its own ccw rotation for bsso portion (rarely done i beleive)
-----------------------------------------------------
Things that change true gonial angle:
chin wing
implants
gonion fillers (if the goal was to lower angle and not just increase width)

Things that change "perceived gonial angle" ie angle btw horizon and mandible in side profile:
Titlting head jfl
any osteonomy that upswings maxilla.. causing mandible to follow ex) lefort

High gonial angle ... low "perceived" gonial angle (look at the alien tier angled ramus)

Low gonial angle + low "perceived" gonial angle. (look at how ramus is vertical compared to joralien barrett)

"perceived" gonial angle >> actual gonial angle... B/c remember.. foids dont walk around with protractors and rulers
